# HTTPS Guidelines

> Learn about the standard HTTPS guidelines for APIs that Suki uses

Suki uses **standard HTTP status codes** to indicate the outcome of an API request.

* **`2xx` codes** indicate success.
* **`4xx` codes** indicate a client-side error (e.g., you omitted a required parameter or provided an invalid configuration).
* **`5xx` codes** indicate a server-side error on Suki's end. These are rare.

The following table lists the most common HTTP status codes you may receive.

| Code                     | Title             | Description                                                                                                                               |
| :----------------------- | :---------------- | :---------------------------------------------------------------------------------------------------------------------------------------- |
| **`200`**                | OK                | The request was successful.                                                                                                               |
| **`201`**                | Created           | The resource was created successfully. The URL for the new resource is in the `Location` header.                                          |
| **`204`**                | No Content        | The request was successful, and there is no content to return.                                                                            |
| **`400`**                | Bad Request       | The request was unacceptable, often due to malformed syntax or a missing parameter.                                                       |
| **`401`**                | Unauthorized      | The request was not authenticated. This could be due to missing, invalid, or insufficient credentials.                                    |
| **`402`**                | Over Quota        | The request was valid, but you have exceeded your plan's quota or rate limits.                                                            |
| **`403`**                | Forbidden         | The request was not authenticated. This could be due to missing, invalid, or insufficient credentials.                                    |
| **`404`**                | Not Found         | The requested resource does not exist.                                                                                                    |
| **`409`**                | Conflict          | The request conflicts with the current state of the resource (e.g., the resource already exists, or the request was based on stale data). |
| **`422`**                | Validation Failed | The request was parsed correctly but failed a validation rule.                                                                            |
| **`429`**                | Too Many Requests | You have sent too many requests in a short period. We recommend using an exponential backoff strategy for your requests.                  |
| **`500, 502, 503, 504`** | Server Errors     | An unexpected error occurred on Suki's servers.                                                                                           |
